So...the S2 has just been in my ears like three minutes, so this is by no means is an endorsement one way or the other. I do want to say something about them now since - to be honest - I purchased these with very low expectations for some stupid reason (usually Dsnuts and Dannybai are on the money). Also, the X1 headphone is so wonderful to my ears that I don't know why I wasn't feeling high on the S2. I think because I've read some not so-good reviews outside of my trust hi-fi buddies, and didn't listen to my motto: YOU HAVE TO HEAR IT YOURSELF!
Okay, that's out of the way and it's been about 10 minutes. First thoughts:
- More bass than I thought. Not M200 level but not too far behind
- Fuller sound than I've ever imagined
- Vocals forward and detailed, but not as clear and as transparent as the M200 (my universal standard at the moment along with the ASG-2).
- More neutral sounding than the M200
- Nice detail sound, but not on the M200 level, but again, not far behind
- Fit is fantastic for my ears
- The soundstage is not as wide as the M200, but it's not too small either
So take all these thoughts with a grain of salt, but out of the box the S2 is not bad at all! I expect it to get better (with more clarity and details with burn-in).
Does this sound like an IEM version of the X1? See, to be honest I can't remember how the X1 sounded to me out of the box, but where the X1 is now (and with the silver Zu cable on it) I would have to say no. The X1 is for more detailed with greater imaging, clarity and instrument separation. Is the sound in the Philips Fidelio family? Definitely! And I expect it to get better, but again, these earphones sound very very good out of the box (pointing upper tier instead of mid or lower tier). I can't say what other earphones sound like this Fidelio though. It sounds with very neutral with bass. It does, however, seems to have its own sound signature (which is a good thing to my ears). More later. Oh, it doesn't sound like the M200 to me at all, but there are some similar qualities (like both have wonderful timbre).
